Mark Zuckerberg Net Worth

Mark Zuckerberg has an estimated net worth of $238 billion, according to Forbes Real-Time Billionaires, Mark Zuckerberg profile (figures as of October 20, 2026). That is up from $62.3 billion in 2019.

Mark Zuckerberg is an American businessman, programmer, and webmaster who co-founded Facebook and its parent company, Meta Platforms. He is chairman, chief executive officer, and controlling shareholder. He briefly attended Harvard College, where he launched Facebook in February 2004 with Eduardo Saverin, Andrew McCollum, Dustin Moskovitz, and Chris Hughes. The site began as a student directory that matched names with photos, then quickly spread from Harvard to other schools.

His wealth comes mainly from the company he built and later took public in 2012. Forbes says Zuckerberg owns about 13% of the company’s stock. Facebook changed its name to Meta in 2021 as the business shifted toward the metaverse, and later toward AI. Forbes puts his net worth at $238 billion on its real-time tracker as of October 20, 2026, placing him among the world’s richest self-made people.

How Mark Zuckerberg built his fortune

Zuckerberg’s money story starts with Facebook, the social network he began in 2004 while at Harvard. He wrote the code and launched the site with a group of roommates. After leaving Harvard, he and the co-founders moved to Palo Alto and kept building the company. That early push turned a campus project into a large technology business. Forbes identifies Facebook as the source of his wealth and places him in the technology industry.

A big turning point came in 2012, when Zuckerberg took Facebook public. Forbes says he now owns about 13% of the company’s stock, which helps explain why most of his fortune is tied to the business. In 2021, Facebook became Meta as the company aimed at the metaverse, and it later shifted again toward AI. Outside the company, he and Priscilla Chan pledged in 2015 to give away 99% of their Meta stake over their lifetimes.

How Forbes' estimate moved

Forbes tracked major swings in Zuckerberg’s wealth across the past several years. Its estimate was $62.3 billion in 2019, then $54.7 billion in 2020. It climbed to $97 billion in 2021 before falling to $67.3 billion in 2022 and $64.4 billion in 2023. Those changes happened during a period when the company changed its name to Meta, focused on the metaverse, and later turned more attention to AI.

The rebound was sharp after that. Forbes estimated Zuckerberg at $177 billion in 2024 and $216 billion in 2025. On Forbes’ real-time billionaires tracker, he stands at $238 billion as of October 20, 2026. His fortune remains closely linked to Meta because he still owns about 13% of the stock. Forbes also notes that he and Chan are spending $3 billion in an attempt to end, cure, or manage all disease by 2100.
